Most believe that the only function of a roof covering is to provide a material to shed water, but of equal importance is its ability to provide thermal protection. In a house with a cathedral ceiling, the roof forms the ceilings of the rooms below. A dark colored shingle will affect the interior environment by absorbing solar heat from the sun during the day. This same roof, on a clear, cool night will transmit more heat from the house than would a light colored roof. A white or nearly white roof will reflect solar radiation during the day and will not radiate much heat at night. Unfortunately the roof has to stay relatively clean if it is to function properly.
